Adnexal Teratoma

Background: Adnexal torsion is a gynecologic emergency that requires surgical treatment. In this study, we reviewed the surgical outcomes of women with adnexal torsion in eastern Taiwan (Hualien county, area 4,629 km2 , 330,000 residents). Methods: This retrospective study included 42 women diagnosed with surgically-proven adnexal torsion from January 1, 2010, to September 31, 2015. We compared the symptoms, objective findings, and surgical outcomes of patients who underwent laparotomy or laparoscopy...

This retrospective study aimed to evaluate the sonographic diagnosis and management strategy of symptomatic adnexal torsion at a teaching hospital in Hyderabad, India. All women with abdominal pain and preoperative or operative diagnosis of adnexal torsion from January 2011 to December 2015 were included. A total of 76 women with 78 episodes were included; 28 (36%) occurred during pregnancy. The ovarian mass (in 71%) and pregnancy (in 35%) constituted the most common risk factors. The overall sensitivity, specificity, positive predictive value, negative predictive value and the accuracy of ultrasound were 75%, 27%, 86%, 15% and 68%, respectively...

Sebaceous carcinomas are rare tumors, with the majority of described cases occurring within the eyelid. To date, there are nine documented reports of sebaceous carcinoma arising within a mature cystic teratoma of the ovary. Although the majority of cases originate from idiopathic mutations, there exists a strong association between this rare tumor and hereditary syndromes of DNA mismatch repair deficiency, such as Lynch syndrome and the lesser-known Muir-Torre syndrome. Here we present the case of a 67 year-old woman with a longstanding history of a small left ovarian cyst with sonographic features of an ovarian dermoid...

AIMS: To describe the ultrasound features of benign struma ovarii that often mimic ovarian cancer in the background of complex clinical and histopathological pictures. MATERIAL AND METHODS: We retrospectively identified patients with histologically confirmed benign struma ovarii, treated in our institution between 2003-2016 with complete imaging, clinical, nd histopathological data available. Ultrasound findings were drawn from images, and reports using terms and definitions of the International Ovarian Tumor Analysis group and pattern recognition description was applied...

Background: Cryopreservation of oocytes is an efficient method of fertility preservation (FP) that can be applied in women suffering from gynecologic conditions that menace their reproductive future. Collection of oocytes becomes challenging in some scenarios, like the possibility of an ovarian cancer, the " ex-vivo " harvest of oocytes for FP, aspirating follicles directly from the ovarian specimen already excised by laparotomy or laparoscopy and it is an option for these cases...

PURPOSE: Adnexal torsion constitutes 2.7% of gynecological emergencies, it is more frequently seen in reproductive age. Delay in diagnosis and treatment may lead to loss of the ovary. In this study, we aimed to assess patients who had adnexal torsion and compare laparoscopy with laparotomy in the treatment of these patients and point the most appropriate surgery according to age groups of the patients and comparison of patient characteristics and management between adnexal torsion in postmenopausal and premenopausal patients...

Mature ovarian teratoma is the most frequent benign tumor in premenopausal women. It is usually asymptomatic but complications are possible such as adnexal torsion, infection, malignant transformation or cystic rupture. The latter can be spontaneous or more often occurs during surgery of excision of dermoid cyst. It can rarely result in chemical peritonitis, which is due to the irritation of the peritoneal serosa by the aseptic content of the tumour. We report the case of a patient who undrewent an emergency laparotomy for a chemical peritonitis following a spontaneous rupture of a dermoid cyst...

Ovarian masses are one of the most frequently identified entities in gynecological practice. Early differential diagnosis is a key factor in the medical management of each patient. Transvaginal ultrasound along with additional preoperative testing, such as serum cancer antigen 125 (CA-125) levels and the Risk of Ovarian Malignancy Algorithm (ROMA) score, usually provide sufficient information for a presumptive diagnosis. Minimally invasive surgery as a therapeutic approach is the standard procedure for uncomplicated and benign adnexal masses...

RATIONALE: This report describes a Successful treatment of anti-NMDA receptor encephalitis with early teratoma removal and plasmapheresis. PATIENT CONCERNS: We present a 31-year-old Caucasian nulliparous patient who was admitted as an emergency with general illness status accompanied by holocranial cephalalgia and fever. DIAGNOSES: The previous symptoms were followed by disorientation, persecutory delusion, incoherent language, and tonic-clonic seizure...

STUDY OBJECTIVE: Adnexal torsion (AT) requires urgent surgical intervention to preserve ovarian function. Historically, treatment for AT was oophorectomy because of concerns related to leaving a nonviable ischemic ovary. No published studies support these theoretical concerns and current literature supports conservative management. The aim of this study was to review the institutional outcomes for AT cases, including salvage rates and complications. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This study was approved by the institutional review board at Baylor College of Medicine...

OBJECTIVE: Examining the cases of mature cystic teratoma (MCT) that are diagnosed and treated in our clinic regarding their association with fertility; and detecting the rate of malignant degeneration and the types of malignancies. MATERIAL AND METHODS: Patients, operated due to adnexal mass between April 2012 and August 2017 and diagnosed with MCT, were retrospectively examined. Mean age of the 80 cases, which met the criteria, was 30.60±10.5. 9 were suffering from infertility, according to hospital records...

Anti-N-methyl D-aspartate receptor (NMDAR) encephalitis is a paraneoplastic, immune-mediated encephalopathy with a known association with ovarian teratomas. We present the first case in the UK of a 7-year-old patient presenting with this condition. Having been previously fit and healthy, the patient presented with an acute onset of cognitive disturbances. The initial suspicion was that of an infective encephalopathy; however, the lumbar puncture results were negative. Electroencephalography reported diffuse background slowing, supporting a diagnosis of encephalopathy...

The potential complications associated with an adnexal mass discovered during early pregnancy call for surgical treatment. Ideally, surgery is performed after gestational week 12, but uterine expansion after the first trimester makes surgery difficult. We report two pregnancies complicated by adnexal masses for which we used an organ fixation device for safe performance of single-site umbilical laparoscopic surgery. Pelvic magnetic resonance imaging depicted a dichorionic, diamniotic twin pregnancy and 60-mm right adnexal mass in the first patient and bilateral adnexae in the second...

We describe a case of a mature cystic teratoma of the ovary with high proportion of solid thyroid tissue (< 50% of the entire tumor) in a childbearing woman. The patient presented with non-specific abdominal bloating. Pelvic ultrasound and magnetic resonance imaging revealed a complex cystic-solid tumor confined to the left ovary with an anterior fat-containing locus compatible with mature cystic teratoma and a posterior predominantly solid component with low signal intensity on T2-weighted images that was histopatologically diagnosed as benign thyroid tissue...

Struma ovarii (SO), a rare tumor containing at least 50% of thyroid tissue, represents approximately 5% of all ovarian teratomas; its malignant transformation rate is reported to occur in up to 10% of cases and metastases occur in about 5-6% of them. We describe a 36-year old woman who underwent laparoscopic left annessectomy two years earlier because of an ovarian cyst. Follow-up imaging revealed a right adnexal mass, ascitis and peritoneal nodes that were diagnosed as comprising a malignant SO with peritoneal secondary localizations at histopathology performed after intervention...

Tuberculosis (TB) remained as one of the top 10 causes of death worldwide despite an overall decline in its incidence rate globally. Extrapulmonary TB is uncommon and only accounts for 10-20% of overall TB disease burden. Abdominopelvic TB is the sixth most common location of extrapulmonary TB. The symptoms and signs are often insidious and nonspecific. Diagnosing abdominopelvic TB can be very challenging at times and poses great difficulties to the clinician. Infection with nontuberculous Mycobacterium (NTM) is even rarer especially in an immunocompetent patient...

OBJECTIVE: To assess the natural history of ultrasonographically diagnosed benign ovarian teratomas in asymptomatic women. METHODS: We conducted a retrospective observational cohort study of 408 women (mean age 36.6 years, range 14-81 years) diagnosed as having an ovarian teratoma by transvaginal ultrasonography (except eight who only had a transabdominal study done) between January 2003 and December 2013 at a single tertiary care institution. Six hundred thirteen women were diagnosed with ovarian teratoma of whom 205 were promptly treated surgically, leaving 408 patients followed conservatively with follow-up scans at 3 and 6 months from diagnosis and then yearly...

The differential diagnosis of cystic adnexal masses includes various pathologies, some placed extragonadally. Herein, we present two different cases of omental ovarian dermoid tumours that were diagnosed using ultrasonography and removed with surgery. The greater part of the omental teratomas appear to have developed from self-amputation of cysts in the ovary, followed by their re-implantation into the omentum. Omental teratomas can be located in the pelvis, where they might be mistaken for an adnexal mass, an upper abdominal mass, or a periumbilical mass...

BACKGROUND: Serum tumor markers are widely used for the preoperative evaluation of an adnexal mass. Elevations of cancer antigen (CA) 125 and CA 19-9 have been reported in patients with mature cystic teratoma (MCT). The aim of the study is to investigate the relation of serum tumor markers with tumor characteristics in young women with MCT. METHODS: We conducted a retrospective review of 157 patients under the age of 35 who underwent laparoscopic surgery for ovarian MCT...

Autoamputated ovary with mature cystic teratoma (MCT) is a rarely reported gynecologic entity with an unknown prevalence. A 34-year-old woman referred to our clinic for presumed left ovarian tumor. Pelvic examination, ultrasonography and computed tomography scan revealed a 5-cm, cystic ovarian mass with calcification and fat component, and tumor markers were as follows, cancer antigen (CA) 125; 10.4 U/mL, CA19-9; 2 U/mL. Laparoscopy was performed. The mass was identified in the left adnexal region without any ligamentous or direct connection with the pelvic organs...
